GHC 8.0.2: use -split-sections -split-sections replaced -split-objs with following upsides: 1) -split-objs adds considerable overhead to compile time 2) combined with stripping, it causes issues when cross-compiling For upstream see https://ghc.haskell.org/trac/ghc/ticket/8405 This is supported only for Linux/Windows using ld linker. GHC master also turns on -split-sections by default.

generic Haskell builder: don't copy packages from GHC In order to build the package databases that we will use when compiling a Haskell package, we iterate over the relevant dependencies, and if they contain a package db, we copy its contents over. So far so good, except when one of those dependencies is GHC. This doesn't happen ordinarily, but it will happen when we construct the package database for compiling `Setup.hs`. This is compiled for the build architecture, so we get the build deps, including both the native and the cross GHC (if there is one). In this case, we end up copying the packages from the GHC's package database. This is at best unnecessary, since we will get those packages from the GHC when we compile with it. At worst, however, this is semantically questionable. We can end up having multiple copies of e.g. Cabal with the same version, but (potentially) different contents. At the moment, GHC will expose one of these at semi-random depending on which one it looks at "first". However, there is a MR open [in GHC](https://gitlab.haskell.org/ghc/ghc/merge_requests/545) which as a side effect will instead expose both, leading to ambiguous module warnings (which is not unreasonable, since it *is* ambiguous). So what can we do about it? The simplest solution is just to not copy the package databases from GHC. GHC is special in this regard, so I think it's okay to treat it specially. This PR should have no effect on anything now, but will prevent any breakage when/if the GHC patch lands. Closes https://github.com/NixOS/nixpkgs/pull/57706.

#
# We don't need to, since those packages will be provided by the GHC when

# ambiguous.
